So I had my period from July 20th 2020 to July 25th 2020. I have a 24 day cycle usually. I had sex after my period all the way to August 3rd. Around 5dpo according to my app, I woke up to dried brown spotting in my underwear that had a tiny bit of pink in some spots. Only lasted for an hour or two. Then 12dpo (day before predicted period) I had thick white discharge. Today I am one day late (was supposed to be here yesterday) and I'm still having creamy white discharge. I took a FR pregnancy test and it was negative. Any advice?
